Why is silicone a good semiconductor?
Silicon elements are able to bind atoms tightly and in complex arrangements. The abundance of silicon makes it inexpensive and easy to acquire. This is the biggest reason why silicon is the most widely used semiconductor material.
Is silicon a conductor or an insulator? Pure silicon is a semiconductor, and its properties lie halfway between good conductors and good insulators, it can conduct electricity as well as behave as an insulator under specific configurations and environmental conditions.
MIT researchers say cubic boron arsenide is the best semiconductor material ever found, and maybe the best possible one. Silicon is one of the most abundant elements on Earth, and in its pure form the material has become the foundation of much of modern technology, from solar cells to computer chips.
Pure silicon and germanium are poor conductors of electricity because their outer electrons are tied up in the covalent bonds of the diamondlike framework.
One of the major disadvantages of silicone rubber is its poor tear strength. This can be improved with the addition of other ingredients, but it doesn't naturally offer strength or abrasion resistance, so the application needs to be carefully assessed for the suitability of silicone as a solution.
Causes. The global chip crisis is due to a combination of different events described as a perfect storm with the snowball effect of the COVID-19 pandemic being the primary reason for accelerating shortages. Another contributing factor is that demand is so great that existing production capacity can't keep up.
Silicone encapsulants and coatings are safe and offer protection for the delicate electronic components from harsh environments.
Silicon, a very common element, is used as the raw material of semiconductors because of its stable structure. Purification of Silicon consumes large amounts of power.
Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor.
The most common 2-D material replacing silicon is graphene. Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice.

Liquid silicone rubber consistently maintains its electrical properties, even when subjected to environmental conditions such as temperature fluctuations and moisture. These attributes attest to silicone rubber being a great insulator for high-voltage components, transformers and other electrical equipment.
Silicon itself is not magnetic and efforts so far to dope it with magnetic metals have disrupted its crystal structure, vastly reducing its ability to conduct electricity.
On the other hand Silicon reacted as a semiconductor.So Silicon have the ability to conduct electricit. But diamond has a much higher band gap than Silicon.So diamond doesn't conduct electricity but Silicon does.
Silicone is more environmentally friendly than plastic. It is made from silica, which is derived from sand, and manufacturing silicone does not involve mining for crude oil, which most plastics are made from. It is also more durable than plastic so it lasts longer.
Silicone is extremely durable and significantly more ocean-friendly than plastic since it doesn't break down when lost in the environment into micro pieces like plastic does. Furthermore, silicone lasts longer, and stands up much better against heat (even in commercial dishwashers!) and cold than plastic alternatives.

Silicon, Si, the element, will never be depleted. It is the second most abundant element in the earth's crust. Silicon, however, comes in compounds and a lot of energy is needed to separate the silicon from things like oxygen (beach sand is almost exclusively.
Why is silicon so valuable?
Silicon is one of the most useful elements to mankind. Most is used to make alloys including aluminium-silicon and ferro-silicon (iron-silicon). These are used to make dynamo and transformer plates, engine blocks, cylinder heads and machine tools and to deoxidise steel. Silicon is also used to make silicones.
Silicone is highly sought after for making products such as keypads and devices because of its flexibility and resistance to moisture, cold, heat, and UV radiation. It comes in many forms, from solids and liquids to pastes and greases.
Silicon is used for electronic devices because it is an element with very special properties. One of it's most important properties is that it is a semiconductor. This means that it conducts electricity under some conditions and acts as an insulator under others.
Pure silicon is most notably used in technology, where it is used to make semiconductors. Silicone is a polymer, or molecule chain, consisting of a backbone of silicon and oxygen atoms connected to other atoms (usually carbon and/or hydrogen).
Electricity does not conduct in this pure monocrystalline silicon, when silicon is doped with impurities it becomes conductive. But silicon does not have conductivity comparable to conductors, it is very less but much more than that of insulators which is why it is called a semiconductor.
Silicon is the material of choice in the chip industry. Unlike the metals normally used to conduct electrical currents, silicon is a 'semiconductor', meaning that its conductive properties can be increased by mixing it with other materials such as phosphorus or boron.
Hence, Silicon is preferred over germanium.
Compared with pure metals and ionic salts, covalent solids such as silicon are hard and brittle because dislocations do not move in them except at high temperatures.
The energy gap for germanium is less (0. 72eV) than the energy gap of silicon (1. 1eV). Therefore, silicon is preferred over germanium for making semiconductor devices.
Lifetime and MTTF
According to an analysis published at the University of Illinois, chip makers use a MTTF of 20 years, which safely establishes that chips will reliably last the few years that a manufacturer's warranty covers.
Can you make chips without silicon?
A new type of computing chip could be a game-changer. That's because its transistors are not made of silicon. Transistors are tiny electronic switches that together perform calculations. A new prototype uses carbon nanotubes.

As electronic engineers are reaching the physical limits of silicon for semiconductors, researchers at Lawrence Livermore National Laboratory (LLNL) are looking at an alternative material—diamond—as an ultra-wide bandgap semiconductor.
Graphene certainly has the potential to replace silicon in electronics, but it will be dependent on several different factors, including the willingness of end-users to adopt graphene over the status quo (and, in turn, change all their manufacturing methods).
Why is Silicon Better Than Germanium? Silicon crystals have fewer free electrons than germanium crystals at room temperature, which is why silicon crystals are used for semiconductor devices.
Silicon Carbide Withstands Higher Voltages
Because SiC tolerates higher voltages, power systems built on silicon carbide semiconductors require fewer switches in series. This means simpler and more reliable system layouts as well as lower costs for manufacturers thanks to a reduced number of components.

Silicon has historically been used to make transistors because it is a semiconductor, which is a material that is more conductive than an insulator like rubber but less conductive than a metal like steel, according to the Encyclopedia Britannica.
Why silicon is not used in LED?
Since Silicon is an Indirect Band Gap semiconductor so electron cannot fall directly to the valence band but must undergo a momentum change as well as a change in energy. So, energy is released as heat along with the light. Hence, silicon is not suitable for the fabrication of LEDs.
Silicon and germanium are not suitable because those junctions produce heat and no appreciable IR or visible light.
